[Liblas-devel] Drivers

[Adrien Chauve]

Hi there,

> lidarformat (they even use libLAS :) ) is pretty much exactly the
direction I'd like to go except 1) LGPL instead of BSD and 2) source code
layout.
What do you mean by "code layout" ?

> Ok, I'm not so concerned about license at all as long as there is a
collaborative project behind it with some weight.  I don't know if
lidarformat (bad name IMO) has that yet.
Actually there is not a strong collaborative project behind lidarformat, and
lidarformat *is* a poor name that I would like to change.

Lidarformat is designed to handle point clouds as vector<Point> where Point
is a data structure known only at runtime. This structure is described in an
xml file (here<http://code.google.com/p/fullanalyze/wiki/UserGuidePointClouds#Point_clouds_file_formats>is
an example). A few templates are used to have almost the same
performances as if the point cloud was implemented as a real vector, but
some parts still need to be refractored (especially the iterators should be
based on boost iterator facade instead of being hand-coded).
Of course LAS is one of the format that should be supported by the library,
but it is currently broken.

Is that what you have in mind for liblas ?

Actually lidarformat is the base of another project dedicated to
full-waveform lidar data management and visualization
(Fullanalyze<http://code.google.com/p/fullanalyze/>),
but the fullwave format is still a draft mainly adapted to Riegl data. So
it's still a part of the FullAnalyze project and is not available as a
standalone library. I don't know if it would fit with Leica data and LAS
1.3.

Best regards,
Adrien
